ISP Config volume expanded on Amazon EBS. Subdomains are still full?

I have isp config 3 installed on a amazon instance that was at 8gigs and i have expanded it up to 30gigs now. But my subdomains still see that the drive is full. Is there some configuration file or something i need to restart with isp config?

I have a Ubuntu instance with ISP config 3 running on that. I have multiple subdomains which i use for demos that i have. Recently my drive became full so i made a snapshot or my EBS, created a larger volume from the snapshot and replaced it in /dev/sda1. The instance recognized that there is more space but the subdomains do not. The subdomains will not recognize the increased size
